COVAR_POP

COVAR_POP returns the population covariance of a set of number pairs.

Syntax

COVAR_POP(<expr1>, <expr2>)

Arguments

ArgumentsDescription
<expr1>Any numerical expression
<expr2>Any numerical expression

Return Type

float64

Example

Create a Table and Insert Sample Data

CREATE TABLE product_sales (
id INT,
product_id INT,
units_sold INT,
revenue FLOAT
);

INSERT INTO product_sales (id, product_id, units_sold, revenue)
VALUES (1, 1, 10, 1000),
(2, 2, 20, 2000),
(3, 3, 30, 3000),
(4, 4, 40, 4000),
(5, 5, 50, 5000);

Query Demo: Calculate Population Covariance between Units Sold and Revenue

SELECT COVAR_POP(units_sold, revenue) AS covar_pop_units_revenue
FROM product_sales;

Result

| covar_pop_units_revenue |
|-------------------------|
| 20000.0 |
